The Anatomy of a Neutron

Neutrons have the reputation of being dead weight, mere ballast in the atom. But it turns out that we have not been looking at a high enough magnification to see what’s really going on. Recent studies with particle accelerators have shown that the neutron has its own life, with a surface that boils with news particles and a heart alive with quarks and gluons. In fact, at tiny distances, neutrons may not even be entirely neutral.
